.DISCUSSION...

Transient low pressure to the west will maintain mild temperatures
today with daytime highs in the 60s and 70s. A relatively more
favorable overlap of instability and moisture will support a low
probability of showers and isolated storms from Alpine-Mono counties
into S.Lyon-Mineral counties this afternoon. A stray afternoon
shower may also develop near the Tahoe Basin, but confidence is low.

A persistent troughing pattern remains in place throughout the week,
allowing temperatures to slowly warm to late June standards leading
up to the holiday weekend. While most areas will stay dry this week,
each afternoon will feature low chances (10% or less) of an isolated
shower or a stray thunderstorm. Winds will become breezy each
afternoon this week -- especially Tuesday and Thursday -- but
winds aren`t expected to be stronger than our typical zephyr
breeze. Still, breezy conditions may pose minor impacts to fire
and recreation at times.

The Independence Day weekend is trending towards being a hot one as
temperatures sharply warm-up in response to building high pressure.
Daytime highs are slated to breach the 80s for Sierra communities
and 90s across NE CA/W NV valleys over the weekend. While there is
no strong signal for widespread thunderstorm activity this weekend,
warming surface temperatures tend to support at least some potential
for thunderstorms across the higher Sierra terrain. If you have
outdoor plans to celebrate the holiday, be sure to frequently check
the latest forecast.
